18 Claims. .(Cl. 232-515) This invention relates to coin disposal units.

adapted for use in coin operated devices suchas a telephone coin collector. V

An object of the invention is to provide a sim plified mechanism of increased efiiciency for dis posing of the coins deposited in a coin operated device.

In accordance with one embodiment of the in vention as applied to a telephone coin collector,

the coin disposal unit comprises a coin hopper.

having a normally unsupported coin t'rapybelow which lies the entrance to a coin collectschute oted vane or other snitablejmeans un cer the control of a relay and located below the coin trap serves to deflect deposited coins. into the'collect chute or the refund chute,.as may be desired.

l'n order that any deposited coin may be ternporarily held in suspense on the coin trap, the coin disposal unit includes means-for latching. the

' rap in coin supporting position which becomes immediately effective in response to the initial downward movement of the trap produced when the trap is struck-by adeposited coin. This initial trap movement also serves. to upset; a" trigger to permit, the closing of electrical contacts associated with a coin relay'whereby the relay may be subsequently energizedto-release the trap latch and establish the coin defiectingvane in .the proper position for insuring the desireddisposal of the deposited coins. .A iurther-feature of the invention is the avoidance of widely separated points of application of the relay dis: placement to the mechanism to be actuated whereby a much more compact coin disposal unit is realized. In accordance with-a further feature.

of the invention, the time of operation of the relay is in no way a function'of thetime required for the coins to leave the trap since the trap is permitted to stay in coin discharging position until the last coin has been discharged therefrom even though in the meantime the relay has become deenergized. i Referrin to the drawings: 1 t Fig. 1 is a side view of a telephone coin c01- lect-or embodying a coin disposa-lunit of this invention; v J

the a ocia-ted Y and pin 21. Fastened to one end of pin 21 and rotatable therewith is a relatively heavy counterweight or inertia member 3| having a radial slot 32. Integral with trap 2| is an angular arm 33 having a lateral extension 3d 7 which passes through and beyond the slot Surrounding the cylindrical portion 35 of counterweight 3| are several turns of a biasing spring 25 which has one end fitted into an aperture'ilfi in trap extension 34 and has its other end secured in aperture 31 in counterweight 3| whereby extension piece 34 is biased to engage the side wall 38 of slot 32 in the absence of a coin load on trap 2 i. It is to be noted that there is a delayed motion connection between the counterweight 3| and trap 2| determined in amount by the width of slot 32. 3| remote from coin trap 25 is a vertical bracket Mounted on the face of counterweight 45Iior supporting a fixed pin ii about which is pivoted a trigger 22, with pin ii being substantially perpendicular to a plane passing through the trap pivoting axis 21.. a

On one side of hopper 2k? is mounted a bracket 43 for supporting a horizontally arranged electrical spring pile-up comprising a pair ofnormallyclosed spring contacts 543- and 35 and a pair of normally open spring. contacts 48 and 4?.

(Figs. 4 and 4A). Trigger &2 has an arm 68 lying between springs 45 and 46 and. carries at its free end a stud 59 which engages springs t and 46 at points aligned with the, axis of pin 27. Spring 45 is strongly tensioned to exert pressure on trigger arm iii to cause rotative movement of trigger 42 about its axis ti and a' closure of contacts 45 and 47 butspring ii is restrained from so doing by reason of the fact that a second arm 5| of the trigger normally lies against the end of traparm 34 (Fig 12), with trigger arm 5| extending only'a short distance beyond the ture carries an insulating stud 59 which lies beneath the free ends of the spring pile-up, with contact spring 4'! having an extension comprising a lateral arm 5?" and adownwardly directed tab 51, with tab 51 lying adjacent stud 56 and in the path traversed by stud 56 when the relay armature is moved to its attracted position. The means forholding the armature 5 4 in its unoperated position is a suitable'b-iasing spring 38. The limits of the armature travel are determined by a fixed pin 58 which is supported in oversize holesin the relay framework and which passes through slots in the flanged portions of the armature such as slot 59, Fig. 5, with the armature restoring spring (it) normally holding the armature in its non-operated positionof Fig. 5.

The upper edge of the coin deflecting vane 23 coins discharged from trap 2|. In Fig. 11, vane 23 lies against stationary pin 63 to close the entrance tocollect chute 25 and to direct into the refund chute 24 any coins discharged from the coin'trap. External to the coin hopper vane, pin 6| carries an irregularly shaped cam mem ber-64 to enable the vane to be controlled in position by relay armature 54. The lower pertion'of armature E-icomprises a laterally extending arm 65 which lies beneath the winding j of relay 22 and which has at its free end a diag onally disposed slot 66. Also located below the 3) fastened at one end 58 to the relayiramework while the main portion of wire Bl lies in a horizontal position with its opposite end l9 projecting through slot 68 to lie adjacent cam member 64 of coin vane 23. Supported inside the coils ofwire fi'l is an elongated permanent magnet .'||,.one end of which lies adjacent an extension 12 of the relay core. The manner in which wire end H3 engages cam member '84 to selectively set coin deflecting vane 23 in a desired position will be described later. v

' The coin disposal unit is shown in its normal condition in the side, top and front views of Figs. 3, 4 and 5. Before describing the operation of thedevice, it should be noted that the coin trap 2| is normally biased to a coin obstructing posi- It should also be noted, as shown particularlyin Fig. 3, that. the bent end portion 73 of trigger arm M normally lies a short distance below the horizontal tab '35 of the stationary member 16 and that as seen in Fig. 4 the position of stationary tab 75 is such that if the trap 2i and counterweight 3| were rotated by hand the triggerend 33. would just escape being caught bytab 15 in the resulting upward movementof trigger arm 14. I

The operation of the coin disposal unit will now be described, starting with the assumed deposit of a coin in the coin gauge i'l. Such a coin acquires considerable velocity while traversing coin chute l8 and while falling through the upper portion of coin hopper 29 so that the coin strikes coin trap 2| with considerable force. The intertia of'trigger counterweight 3| is considerably greater than the inertia of trap 2| with its extension 33 so that at the instant of coin impact the trap starts moving downwardly while lies well below and out of engagement with the coin trap 2|. Vane 23 is fastened to a horizon tally arranged rotatable pin ii and vane 23 is adapted to occupy either one of two possible. positions, as shown in Figs. 10 and 11.

In Fig. 10, the upper end of vane 23 lies against a stationarypin 52 closing the entrance to refund chute 24 and directing into collect chute 25 any the counterweight 3| tends to remain stationary. As the trap starts; its downward movement its integral arm 34 rotates with it so that with counterweight 3| still stationary, trigger arm 34 moves away from side wall 3810f slot 32 towards the opposite side of the slot and in so doing acts against the tension of spring 29. This initial relative movement of trap arm 3G with respect to counterweight 3| causes the free end of trap arm 34 to slide out from its normal engagement with trigger arm 5|, wherebytrigger 42 is released from the restraining action of trap arm 34 at the time trap arm 34 has reached a point about half way between the two side walls of slot 32.

Aspreviously stated, trigger 42 is normally biased for movement of trigger arm 5| towards counterweight3| .by reason of the pressure exerted by contact spring 45 .on trigger arm 48. V

.aaenese flfherefore, as soon as trap arm 3 4"has reached a aboutfhalf, way betweenlthe side walls of slotf32, trigger arm fil is released from the restraining action of trap arm.34 to ,permit the .tensioned spring 45 to move trigger arm, Bland spring 45 to the right, as seen in Fig. 4A,v This lateral movement is stopped by the engagement of spring .46 with the relativelystifi spring .41, as

continues its-travel until it strikesthe opposite side wall of slot 32, whereupon the inertia in counterweight 3| is overcome and the counter- .weight starts rotating with thecoin trap; but the rotative movement of counterweight 3| can take place through only a small angle since be- .fore there'can be an appreciable movement of counterweight 3| trigger end [3 hasbeen moved beneath sto '15 to cause their-subsequent engageinent, as shown in Fig. 6, to hold the trap and the -'counterweight in coin supporting position. If desired, coin trap 2| may be arranged to be tilted slightly upwardly prior 'to coindeposit, whereby 'the slight downwardimovement of coin trap 21 caused by coin deposit and ter- I appreciable attractive movement. of I the relay armature has taken place, {Ifhe subsequentro ,minated by engagement of triggerend :13 with 1 stop 75 will leave the trap 2! in asubstantially horizontal coin supporting position; as'shown in Fig. 13. ,t g a After the relative movement of the coin trap with respect to the counterweight to remove the restraining action of trap arm 34 on trigger arm 51, it will be apparent from Fig, 6 that coiled spring 29 cannotat this time move trap arm 34 backinto engagement with slot side wall 3 8jbecause. trigger arm 5i after being released moves towards the counterweight'Sl under the force suppliedby spring 45 so thatthe .end oftrigger arm 5| now lies in thereturn path of trap arm ,34, with trap arm 34 being held away from slot wall3-3 by engagement of trap arm 34 with the end of trigger arm 5| (Figs. 6 and 13). A

The above-described operation lp rodl oed by coin deposit will be. better understogdgby comparing the condition of theapparatusbefore coin deposit (Figs. 3; 4, 5 and .12) with the condition of the apparatusafter coin deposit (Figs 6, 7 and 13), ,Asshown in Eig.'7,'deposited coin il lies onecoin trap :2! and, the-dischargeof the coin is temporarily. Ipreventedby engagement of triggerend l3 with the under surfaceof stop member 75. ,By comparing .Fig-. 4A with Fig. 7A

it will be seen that as a result of coin deposit,

contacts, 41 are closed. A reference 'to the,

spring contacts 44; 45 are'op i d .and spring schematic wiring diagram of Fig. .2 will show,

that the opening of springcontacts lld,45,.by 7 coin deposit removes a short .circuitffrorn the pulsing contacts of calling dial .'8 while the V nosing of spring contacts 45, 4! establishes a circuit to ground through the winding of relay 22 to prepare apparatus at the central ofiice for extending the calling lineto the calledline corresponding to the number dialed by the opera- 7 tion of dial 18 and for subsequently"permitting the application of collect current or refund cur- I collect or refund thedepositedcoinr E'o r illus-' trative purposes, it may be assumed that prior tothelrdepo sit of coin I} thecoindeflecting-Yane *rockyane 23 froni its position against pin-Gite.

There still remains to be described in greater detail the effect or relay operation on trigger'42, counterweight 3i and coin trap 21. ,Aiter coin deposit and when the relay'is energized, either a j by collect current or refund current, the at tractive movement of armature 54movesthe in- 'sulating stud 56 away from the counterweight 3| to engagespring end 51 to move to the left, as viewed in Fig. 7, the free ends of the spring pile-up as well as trigger arm 48. The resulting pivoting movement of trigger not only moves trigger arm #3 outof engagement with stop 15 to permit coin discharge butalso moves trigger arm out of the return path Oftrap arm 34 to permit coiled spring 29 'to again cause the engagement of trap arm-34 with side wall'38 of slot 32.

When relay 22 is deenergized the restoring spring 60 serves to retract armature 54 to its normal position of Fig. 5 thereby moving armature stud 56 towards counterweight 3! to removethe pressure exerted on the spring pile-up by stud 56. Spring 45 due to itsown tension is now free to exert pressure on stud 59 of trigger arm lB but the reengagement of trigger arm 5| with the end of trap arm 34 prevents spring 45 from moving stud 50 far enough towards counterweight 3! to. cause the closing ofcontacts 46 and 41, although" the movement is not suflicient to permit spring 45 to break its contact with srping 44. other words, the withdrawal of the armature from its attracted position to its retracted position permits the spring pile-up and'trigegr 42 toassume their normal positions as they existed It will be noted that even, after the deenergi- ."zation of relay 22 the coin trap 2| may remain in its coin discharging position of Fig. 8 until all coins have left the trap after which the counterweight 3| overbalances the unloaded trap to move the trap back'to its'normal substantially, horizontal position of Fig. 12, to which position counterweight Si is free to move the trap by reason of the fact that trigger arm 13 is again held out of engagement with stop 15. posal unit is now completely restored to normal with all parts ready for a repetition'of its cycle of operation upon the deposit of another initial coin. v

The cycle of operation of the coin disposal unit-may be summarized as follows: The trigger 42 is upset, when a coin hits trap 2| which act .closes the ground circuit contacts 46, 4'1 and opens the dial shorting contacts 44,45 (see Fig. 7A).

In addition,a catch extension 13 of the'trap mechanism operates to support the: trap and When the coins are to be disposed of the pilot magnet operated selector"!!! moves'fto the proper position in armature slot 66 where upon the armature in closing locates a coin se- The coin dis-- of operations, an inertia tripping device is" em} ployed. The inertia is represented-by theftriggei' 1 mounting or counterweight 3| which is free to rotat'e'with the coin trap; that is, the trigger 4 2 and the trap catch extension 13 also rotate with the trap. A minimum frictional moment is attained-at the connection to the fixed set of contact springs 44 to 41 by having springs 45, 46 bear on the trigger arm 48 at the center of rotation. In

addition to this freedom of rotation, there is'provided a difierential motion of limited amplitude between the trigger42 and a rigid extension 34 from the coin trap. Normally the trigger arm 5| rests on the trap extension 34; the trap being held substantially horizontal by counterweight 3 I with the differential motion being taken up by a light spring'force (spring 29 operating between the trap extension 34 and the trigger mounting 3i. When a coin'is deposited its impact on the trap moves the'lightweight trap before the'heavier triggermechanism 3! can get in motion; Thus the trap extension'34- slides from under the arm 5| of the trigger which then trips, closing ground contacts 46, 47. The trap catch 13 which forms a part of the trigger closes under an extension of the framework and thereafter the trap,the coins and the entire rotatable mechanism are re strained'irom further motion. This entire action takes'place in an extremely short interval of time and with but slight displacement ofthe various parts. In disposing of th coins, the relay force applied by stud 56 through ground circuit contacts 46'," 4'5 swings the trigger to release catch 13 and the weight of the-coins on the trap serves to drop the trap to coin discharging position. Simultaneously the difierential between .the trigger 42 "and the trap extension 34: is taken up by biasing spring 29 so that the trigger resets quickly and is ready for the next deposit. The trap meanwhile remains open until the exit of V the last coin whereupon it swings shut freely.

Whilean advantageousembodiment of the in} vention has been described above, it is'to be understood that the invention is not limited 2.
